Earlier this week, Google Voice opened to everyone in the U.S.. The phone management app is great, but even cooler hacks exist just under the hood. Here are our favorite tricks every Google Voice user should know about.

9. Set as Your Skype Caller ID

Free internet calling service Skype is a really cheap way to make phone calls to a landline from your computer. One big downside, though, is those you're calling probably don't recognize the caller, and your number might change every time you call. Google Voice set up their servers, though, to allow setting your Google Voice number as a Skype caller ID. Commenter downdb explains the step-by-step process, which generally involves confirming a text message code and waiting for Skype to change your number.

A Google Voice number, one that rings all your phones, makes good sense as the caller ID number for …

8. Use Your Location to Determine Which Phones Ring

You can set up time-based rules for your phones in Google Voice—so, for example, your home phone doesn't ring from 9 a.m. to 5 p.m.—but not everybody works a regular schedule. Chad Smith, a Wichita-based geek who loves him some Google Voice, set up a clever means of syncing Google Voice with your GPS location, using some PHP scripting and the Locale geo-location app. When you're away from home, you can have only your cellphone ring. When you're at home, you can have a VoIP line and your home line ring. If you're not rocking your own PHP-friendly server space, there's a somewhat beta-level app in the Market, Google Voice Locations (scan-able QR link here) that accomplishes much the same kind of GPS-aware phone management.

7. Use "Do Not Disturb" to Get Work Done

If you've managed to make Google Voice your one number that rings all your phones, you can enact a cloak of silence when you really need to get things done by enabling "Do Not Disturb" for a certain amount of time. All your calls go straight to voicemail, and nothing buzzes or plays a ringtone. It would be even nicer if Google could delay your SMS for the same time—that's often just as deadly a distraction.

6. Send Yourself Advanced Voice Memos

True, you could use a digital recorder, or just call your own voicemail, to leave yourself a voice memo about something you need to remember later. But using Google Voice, you can have that voice memo transcribed to text, sent to your Outlook inbox at work, backed up forever in Gmail, and smartly delivered just where you need it. Drew Vogel's setup sets up his system so that all his other phones don't ring when he calls himself from one of them, and also gets his note-to-selfs into his Outlook box. Mark Stout's method sets up a special greeting for when he calls ("Record note now"), then has that message sent first to Gmail, then forwarded to cloud-based memory service Evernote. Mix and match settings from the two, and you'll feel like you've got your own personal assistant that lives in the cloud and only wants to help you remember things. (Original posts: Stout, Vogel).

5. Upgrade Your Cellphone Voice Plan to Unlimited

Every major U.S. cellular carrier offers some kind of "pick a few numbers, talk with them for free" plan. You know what happens when you make your Google Voice number one of your "friends"? Yep—unlimited free calls on your cellphone. Since everyone gets a unique Google Voice number, it would be hard for AT&SprintRizon-Mobile to start universally blocking Google Voice from your picks. So, for the time being, enjoy living beyond your cellular talk time means through the magic of whatever business plan Google has for Voice.

Most cellphone carriers provide a feature allowing you a certain number of contacts that you can…

4. Send Text Messages Through Your IM Client

Google Voice's web site is pretty fast and easy to grasp, and there are a few nifty desktop clients, like the Google Voice AIR app, that make it easy to send messages with a click or two. But you've already got an instant communication system set up—instant messaging, in fact—and you can receive, reply, and send SMS through it. GVXMPP hooks together your Google Voice text messaging, your email address, and your IM client, so that when a friend texts you, it shows up as a kind of IM, and when you reply, it goes back to their phone—no extra thought, web tab, or phone reach needed.

2. Use Google Voice SMS and Call Shortcuts from Any Phone

Google Voice has crafted pretty neat mobile apps for Android and BlackBerry phones that integrate Google's free SMS messaging. If you're not on one of those platforms, or don't have any kind of data plan, you can still hide your "real" number behind Voice and benefit from its inbox. Gina explained how to do it with a standard phone. It unfortunately involves saving a kind of "alternate" number for each contact, but most modern phones make that fairly easy. Luckily, you can also use that alternate number to call your contact through Google Voice.

Two blogs now claim, through sources at Google, that a desktop VoIP client for Google Voice is…

We're pretty enchanted with Voice, as you can tell, but there have to be other clever set-ups, third-party tools, and quirky uses we haven't encountered or written about yet. Know of one? Tell us about it in the comments.
